In the case of lithium compound 1 the retro‐Diels‐Alder reaction does not have to be accelerated artificially —quite the opposite! 1 represents a rare case in that it reacts before it can be investigated. It has now been possible to trap 1 as the title compound 2 with solvated iron( II ) chloride. 2 is also of interest with regard to its possible chemical reactions. It is reminiscent of ferrocene, but has a highly distorted π‐system.
